Sorry if I’m misunderstanding but is he saying the 8 million is half his net worth or is there a lot more coming?

Is this post wildly off on his net worth calculation?

Either way, I applaud him for his donations!

I hadn’t heard about the Warren Buffett complete 180 degree change on where his money is going after he dies and that’s really disappointing to read.
